Few fruits are as closely connected to summer as peaches. A ripe peach picked directly from the tree is almost impossible to compare with fruit from a grocery store. The fragrance appears before the first bite, the flesh softens in the hand, and the sweetness seems to capture an entire season of sunshine.
Peach trees (Prunus persica) have accompanied gardeners and orchardists for thousands of years. They are beautiful in spring, productive in summer, and surprisingly ornamental throughout the growing season. Their clouds of pink blossoms often rival flowering cherries, while their fruit has inspired poets, artists, and cooks around the world.
Although peaches have a reputation for being more demanding than apples, they reward attentive gardeners with harvests that simply cannot be purchased. A homegrown peach, warmed by the sun and picked at perfect ripeness, is one of the great pleasures of the garden.
Without pruning, peach trees often become larger while producing smaller and fewer peaches.
Peach trees occasionally face challenges, but many problems can be prevented through good cultural practices.
Peach leaf curl is one of the most recognizable peach diseases. Leaves become distorted, thickened, and puckered.
The disease is caused by a fungus that infects new growth during cool, wet weather.
Fortunately, prevention is much easier than treatment. Dormant-season fungicide applications are highly effective when applied at the proper time.
After autumn leaf drop, the tree enters dormancy. To most gardeners, the season feels finished.
To the fungus, however, winter is simply a waiting period.
A fungicide applied after most leaves have fallen coats the bark, twigs, and buds where fungal spores spend the winter. This first application dramatically reduces the number of spores available to infect new growth.
Many peach growers stop there.
But in regions with wet winters and unpredictable springs—including much of New York—the best protection usually comes from a second dormant spray.
Apply it in late winter or very early spring, before buds begin to open
Many experienced orchardists consider this second spray their insurance policy against a rainy spring.
Choosing the Right FungicideCopper has protected fruit trees for generations and remains one of the most trusted treatments for peach leaf curl.
Many gardeners prefer copper because it is widely available, relatively simple to use, and accepted in many organic gardening programs.
Copper works by killing fungal spores before they enter the buds.
For many home orchards, annual copper sprays provide excellent control year after year.
ChlorothalonilCommercial orchards often rely on chlorothalonil-based fungicides because of their exceptional effectiveness.
Many university extension programs continue to recommend chlorothalonil as one of the most reliable treatments for peach leaf curl.
Used during dormancy, it provides outstanding protection against infection.
Lime SulfurBefore modern fungicides became common, lime sulfur was the traditional orchard remedy.
The strong sulfur smell tends to be memorable. Many old gardeners can instantly recognize it because nearly every fruit orchard once used it during dormant-season spraying.
Brown rot affects blossoms and fruit, especially during wet weather.
Improving airflow through pruning and removing infected fruit can greatly reduce problems.
Peach trees ask for a little attention. They need sunlight, pruning, occasional thinning, and a watchful eye for disease. Yet few fruit trees repay that effort so generously.
A peach tree in bloom is one of spring's loveliest sights. A peach tree loaded with ripening fruit is one of summer's most satisfying rewards.
And when you finally pick a perfectly ripe peach and taste fruit that has never known a grocery shelf, it becomes easy to understand why people have treasured peach trees for more than four thousand years.
